Within J.R.R. Tolkien's conception of the languages of Middle-earth as expounded in the Lhammas, Oromėan is the language phylum to which all Elvish languages, such as Quenya and Sindarin, belong. It is there contrasted with Aulėan, the language phylum of Khuzdul, the language of the Dwarves.

The Oromėan languages are so named because their ancestral language supposedly derives from the speech of Oromė, the Vala of the Forest, who was the first of the Valar to meet the Elves at Cuivienen in Middle-earth.
